Abstract

Ensemble à électrode électroanalytique comportant une électrode de travail électro-conductrice qui comprend un conducteur électrique (15), dont le corps est composé de matière électrolytique (16), séparé de l'environnement analytique par une membrane hydrophobe (18). La membrane présente une conductivité électrique plus importante que le reste du circuit de mesure et est sélectivement perméable à une espèce ionique présélectionnée, de façon à offrir un potentiel de membrane stable. L'utilisation de ce genre d'ensemble nous permet de placer une électrode de référence (20) à l'extérieur de la membrane (18).
